[Elecraft] K2 microphone advice

[John Huffman]

What's the purpose of the 5.6k resistor?

I use a Ten Tec 701 hand microphone with no resistor with good audio.  I use a 
Ten Tec 706 desk microphone with no resistor but it loses some of it's lows. 
Tried substituting a 9v battery fo0r the bias voltage, but it made no difference 
in the audio.  The MD2 and MH2 tend to overdrive my particular KSB2.
